The Science of Fine Hair Structures

The Science of Fine Hair Structures

Corn silk. Baby hair. Soft as down. If you have fine hair, you’re probably familiar with these expressions. Fine hair can be almost angelic-looking in its delicacy, but it is notoriously prone to falling flat and resistant to holding a style. There is an amazing statistic behind why fine hair behaves the way it does, however - one that significantly differentiates it from all the other hair structures and helped Pantene scientists develop care for fine hair with Pantene Fine Hair Systems

The Nature of Fine Hair

The single most important fact about fine hair structure is that it has up to 50% less internal protein than thick hair! It also has an average diameter of roughly 70 microns compared to the roughly 90 microns average diameter of medium to thick hair. As a result, there are a number of unique characteristics about fine hair that need to be taken into consideration when developing hair care and styling products for this hair structure:


Fine hair tends to be more flexible than thick hair, which can cause it to fall flat.


Fine hair is usually weaker and has a lower abrasion resistance than thick hair, which makes fine hair vulnerable to damage, such as hair breakage, split ends, and lifted cuticles.


Fine hair is more resistant to twisting than thicker hair, so it struggles to hold curly hairstyles for any length of time.


Fine hair is often straighter than thick hair.

Style Retention

Style retention decreases with decreasing fiber diameter. Fine hair can have a harder time holding specific hairstyles due to its lack of volume combined with its lack of rigidity and firmness, which scientists have confirmed in the lab.

Though fine hair can be a styling challenge, there are some advantages to it. It tends to be more versatile, reflects light better and is easier to control. There are many ways to enhance body and fullness, starting with the proper hair care regimen. Pantene Fine Hair Systems is tailored to fine hair’s needs

fine hair systems includes a specially selected polymer, called HMPCellulose, for fine hair. A balance of cleaning and condtioning is the first step to lay the foundation in the building process.

Although it may seem counterintuitive, conditioning is actually important for fine hair in order to revive limp strands and protect them from damage. Pantene's fine har conditioners were created to be ultra-light weight so as not to weigh hair down, yet still protect and nourish.

Because fine hair struggles to retain any given style, the pantene fine hair mousse and styling products contain ingredients that help with texture, provde hold and maintain fullness to reinforce hair and create enduring styles.

How to Care for Fine Hair

Celebrity stylist Danilo believes it’s important to understand how fine hair differs from thin hair. Those with fine hair structures don’t necessarily have less hair; they have a smaller hair shaft. This composition, however, rarely holds style direction, hangs flat, can be hard to grow and is prone to hair breakage because it is a weaker hair structure. On the bright side, Danilo enjoys working with fine hair more than any other hair type because it allows him to achieve the most dramatic transformation! Here are some of the must-know facts about fine hair, and some tips to create and hang on to that volume:

An effective shampoo is essential for fine hair, as scalp oils could travel faster down fine, straight hair and accumulate along the hair fibers, making lasting volume a challenge. Because fine hair has a lower abrasion resistance, mechanical forces such as brushing and combing can cause the hair to feel rough and dry, so it’s important to be gentle on your hair when styling it.

When you condition fine hair, apply it everywhere but the crown of your head. This helps to retain volume.

When styling fine hair, first gently towel dry, then run a dryer quickly over your whole head, leaving it slightly damp. Then apply a lightweight styling lotion to the roots.

For maximum lift and volume, use a broad round brush at the roots when blow drying.

For va-va voom volume, roll dry hair in Velcro rollers, apply a light hairspray and hit the rollers with a hair dryer.

For fine but abundant hair:

Fine hair will look thicker and fuller with some layers, but not too many, which could make it look thinned out.

If you want to wear fine hair longer, have the sides cut along a diagonal forward-moving line, so that it will be longest in the front. This strong shape helps fine hair look fuller and the angle helps push hair forward.

For both fine hair and sparse/thinning hair:

Stylists agree that a short cut is best for fine hair, but how short? That depends on the shape of your face.

Round faces look better with a longer, layered cut, which helps slenderize your face.

Elongated faces look great with cuts that have fullness at the bottom, which creates the illusion of width.

Diamond-shaped faces should keep the length below the widest part of the face.

In general, cuts that are intended to be worn behind the ears make it look like you have more hair.
